Hierarchy of Dynamic Models of Nonequilibrium Chemically Reactive Plasma: The Possibility of Initiation of Oscillating Chemical Reactions

摘要

A hierarchy of models of chemically reactive low-pressure plasma was considered. On the basis of the Field-Noyes model as a formal set of homogeneous reactions initiated by plasma-generated reactive particles, the possibility of complex dynamic oscillating reaction modes was demonstrated. The form of the solution of the set of equations was analyzed for the process in the afterglow zone at excess concentration of the plasma-generated reactant and with allowance made for the reactant consumption in chemical reactions, and also for the process in the plasma zone with due regard to chemical feedback. It was shown that the form of the solution is determined by the character of chemical feedback.
